Treatment helps men with testicular cancer who don't respond to initial regimen

Scientists have begun human trials of a revolutionary HIV treatment that genetically modifies people's cells to halt the virus, a conference of international experts in Sydney was told Tuesday.

University of Southern California researcher Songtao Shi and his colleagues experiment with stem cells that can regenerate bone and skin tissue.

Theravitae, an international biotechnology company based in Thailand, claim they have a new possible panacea for dilated cardiomyopathy -- Theravitae's adult stem cell therapy.

Unfortunately, new evidence published in the open-access journal PLoS Biology suggests that this regenerative capacity also declines with age as stem cells acquire functional defects.

Human development has long been seen as a one-way street. During gestation, stem cells were thought to develop into a succession of ever more specialized cells. As Dr. R. Ariel Gomez has discovered, the final identity of these cells is not as definite as once thought.

The jury is still out on whether stem cell banking should be done by private players. The raging debate, however, is not deterring city residents from banking their children's stem cells.

A Monmouthshire couple plan to use the umbilical cord of the baby they are expecting for stem cell treatment for the unborn child's 20-year-old brother.

A new method of adult stem cell growth, designed in the Area of Cellular Therapy of the University Clinic (University of Navarra), has demonstrated its efficacy for its capacity to grow cornea stem cells.

Doctors at Children's Medical Center save Springfield child from a lifetime of ailments and probable strokes.

A special patch placed on a damaged area of the heart regenerates cardiac cells after heart attack and improves heart function, a new study finds.

Red tape has held up the work since 2004, but now stem cell researchers at the University of Utah say they are ready to begin clinical trials for a new stem cell therapy at the veterans' hospital in Salt Lake City. Patients with qualifying heart conditions will have stem cells harvested from their bone marrow and injected directly into their open hearts during surgery

Beike Biotechnology Co., Ltd. today announced that a team led by Dr. Yang Xiaofeng at its collaborating hospital in Shenyang completed a study to assess clinical efficacy, safety, and feasibility of transplantation of peripheral blood stem cells for patients with peripheral vascular disease of the lower extremities.

Delmar Chase, 74, has had two coronary bypass surgeries, stents inserted into his arteries to prop them open, and a pacemaker to keep his heart beating normally. Still, he gets chest pain when he walks even a block.

Scientists have discovered that adult neural stem cells, which exist in the brain throughout life, are not a single, homogeneous group. Instead, they are a diverse group of cells, each capable of giving rise to specific types of neurons.

A startling discovery on the development of human embryonic stem cells by scientists at McMaster University will change how future research in the area is done.

Fat from the tummy or bottom could be used to grow new breasts in a treatment which could be carried out in an hour - or a lunch break.

Living Cell Technologies Ltd is pleased to announce it has successfully transplanted the first of six type I (insulin dependent) diabetic patients in a world-first Phase I/IIa clinical trial under current regulatory standards, using its DiabeCell® pig islet cell transplant.

Genetically modified skin cells could be used to fight a cancer which strikes the very young, a UK study suggests.

Blood vessels that have been tissue-engineered from bone marrow adult stem cells may in the future serve as a patient's own source of new blood vessels following a coronary bypass or other procedures that require vessel replacement, according to new research from the University at Buffalo Department of Chemical and Biological Engineering.

Program at Boston University Medical Center (BUMC) have found that tandem cycles of high-dose chemotherapy and blood stem cell transplantation can help treat patients with immunoglobulin-light chain (AL) Amyloidosis who did not respond to initial treatment with this method.

Early-stage study in mice shows potential of adult blood in yielding insulin-producing stem cells; treatment could side-step ethical debate over embryonic cells.

The use of stem cell therapy to prevent heart attacks is explored in a Comment published in this week's edition of The Lancet.

Dr. Ofer Fainaru from Harvard Medical School and Children’s Hospital Boston, in Boston, Mass., USA, will announce that his team has found that dendritic cells (highly specialised immune cells) support angiogenesis by enhancing blood vessel growth.

Researchers in Slovakia have been able to derive mesenchymal stem cells from human adipose, or fat, tissue and engineer them into “suicide genes” that seek out and destroy tumors like tiny homing missiles.

Researchers from Columbia University Medical Center received a $2.5 million grant from the National Institute of Biomedical Imaging and Bioengineering to use stem cells to engineer soft tissue, developing a process that should ultimately allow scientists to use a patient’s own stem cells to develop tissue for facial reconstruction following disfiguring injuries from war, cancer surgery or accidents.

Vitro Diagnostics, Inc., dba Vitro Biopharma, announced the development of a new method to derive human pancreatic beta islets from adult pancreatic stem cells.

U.S. firm Aastrom Biosciences said Wednesday the first patient has been treated with its adult stem-cell therapy for critical limb ischemia.
